Re: [PSUBS-MAILIST] Using a 0-1000 psi Pressure Gauge for a depth Gauge at depths of 1000 feet

Graham,

Use a water pressure gauge, remarked as Roger has described.  Only cost a
few bucks at the local hardware store.  Be aware of the internal cabin
pressure variables Roger spoke of.  If using it in sea water, check it
regularly between dives and replace as necessary.  Always have a safety
valve between the gauge and your through-hull fitting, so when the gauge
breaks, you can cut off the flow of water before the cabin floods.  (This is
true for any valve / plumbing penetrating the hull).
